FIG. 10 is a greatly enlarged fragmentary portion of the helmet, taken within the circle 10 in FIG. 9.

Referring now to FIG. 1 of the drawings, there is illustrated apparatus 20 for treating a persons hair and scalp, and embodying the features of the present invention; which apparatus 20 essentially comprises chair-like structure 21 in which the person is seated during the treatment of her scalp. Specifically, the structure 21 includes a supporting base 22, a seat indicated at 23 disposed above the front portion of the base 22, a backrest indicated at 24 disposed above the intermediate portion of the base 22, and a main housing 25 supported above the rear portion of the base 22. The back-rest 24 is carried by the front or back-structure 26 that is also disposed above the rear portion of the 'base 22 and that projects from the interior of the housing 25 upwardly and rearwardly therefrom to the exterior and well above the seat 23; and in the arrangement, the bottom of backrest 24 projects downwardly behind the rear end of the seat 23 and closely adjacent thereto. Also, the structure 21 comprises a pair of upstanding arm-rests 27 disposed above the front portion of the base 22 and positioned adjacent to the opposite sides of the seat 23, the top of each arm-rest carrying an arm-rail, as indicated at 28.

The back-structure 26 carrying the back-rest 24 is adjustable with respect to the base 22, so as suitably to vary the angle, indicated at 29, between the center line of the back-structure 26 and the vertical, so as correspondingly to adjust the upward and rearward inclination of the back-rest 24 with respect to the seat 23. This mechanism, not shown, is entirely conventional and may be of the well-known spring and counter-weight type; whereby this mechanism includes a position latch provided with a trip button 30. Thus, when the patron, or person, seated in the structure 21 wishes to decrease the angle 29, she leans forwardly and actuates the trip button 30, so that this mechanism causes the back-structure 26 carrying the back-rest 24 to pivot forwardly; which new position of adjustment of the back-structure 26 is preserved upon release of the trip button 30. On the other hand, when the person seated in the structure 21 wishes to increase the angle 29, she leans backward and actuates the trip button 30, so as to pivot backwardly the back-structure 26 carrying the back-rest 24; which new position of adjustment of the back-structure 26 is preserved upon release of the trip button 30.

Also, the back-structure 26 carrying the back-rest 24 is adjustable with respect to the base 22, so as suitably to vary the effective height, indicated at 31, between the top of the. back-rest 24 and the rear end of the seat 23. This mechanism, not shown, is entirely conventional and may be of the well-known rack and gear type; whereby the mechanism includes a hand-wheel 32. Thus, when it is desirable to adjust the effective height 31 between the top of the back-rest 24 and the rear end of the seat 23, the attendant, or beauty operator, manually rotates the hand-wheel in the required direction in an obvious man- Further, the back-structure 26 carries on the front top central portion thereof a helmet 40 that is positioned at the top central portion of the balk-rest 24 and that is 'worn by the person seated in the structure 21 who is to receive the hair and scalp treatment. More particularly, as shown in FIGS. 2A and 2B, the helmet 40 comprises an outer hood or shell 41 that may be formed of a suitable molded synthetic organic resin, such, for example, as the polycarbonate resin sold by the General Electric Co. as Lexan. The lower front portion of the hood 41 has a substantially annular opening 411; formed therein that accommodates the insertion therethrough of the upper and rear portions of the persons head, so that the hood '41 encloses the persons hair and scalp.

Before proceeding with the description of the construction and arrangement of the helmet 40, it is first noted that the person who is to receive the hair and scalp treatment is first seated in the structure 21. The inclination or angle 29 of the back-rest 24 with respect to the vertical is then adjusted to the comfort of the person; and then the height 31 of the top of the back-rest 24 above the seat 23 is adjusted to the length of the persons torso,

and specifically to cause the helmet 40 to enclose the hair and scalp of the person thus comfortably seated in the structure 21.

I Returning to the construction of the helmet, and again referring to FIGS. 2A and 2B, the extreme top end of back-rest 24 carries a cushion 24a that is adapted to engage the nape of the neck of the person comfortably seated in the structure 21, when the height of the top of the back-rest 24 is properly adjusted above the rear end of the'seat 23, so as comfortably to support the per sons head in upright position while the top and rear portions'thereof are enclosed by the hood 41. The edge about the opening 41a formed into the lower front portion of the hood 41 is suitably reinforced by a metal band '42 that may be formed of stainless steel; and, in turn,

the band 42 carries a composite flexible sealing gasket 43 of generally annular form and that is adapted to engage an annular band of the persons head disposed adjacent to the persons hairline, thereby to form a sub stantially liquid-tight seal between the hood 41 and the engaged annular band of the persons head and to define a chamber 41a within the hood 41 and disposed above and rearwardly of the corresponding upper and rear portions of the persons head thus enclosed in the hood 41. Also, the sealing gasket 43 is so constructed and arranged that it spaces the band 42 radially outwardly from the persons head, so as to accommodate limited turning of the persons head with respect to her torso and with respect to the hood 41 while the person is thus seated comfortably in the structure 21 and is thus wearing the helmet 40, and without impairing the liquid-tight seal between the hood 41 and the engaged annular band of the persons head. More particularly, the composite annular sealing gasket 43 comprises a substantially annular flexible and elastic head band 44 that may be formed of latex, or the like, and having the general construction of the band usually provided about a bathing cap; which 7 head band 44 that may be formed of latex, or the like, and having the general construction of the band usually provided about a bathing cap; which head band 44 directly engages the band about the persons head at her hairline, as previously noted. The elastic band 44 is suitably secured as by an adhesive, in water-tight relation to the inner edge of an annular diaphragm 45 formed of a flexible sheet of water-impervious synthetic organic resin, such, for example, as the polyethylene terephthalate resin sold by Du Pont as Mylar. The outer edge of the annular diaphragm 45 is detachably secured in watertight relation to the metal band 42 employing a number of snap-fasteners, indicated at 46. The extreme front and rear portions of the outer edge of the diaphragm 45 are suitably secured in water-tight relation to the respectively adjacent portions of the hood 41 by snapfasteners, respectively indicated at 47 and 48. Thus, it will be understood that the arrangement of the snapfasteners 46, 47 and 48 accommodates ready placement and removal of the composite sealing gasket 43 with respect to the hood 41 and within the opening 41b formed therein. This arrangement is very advantageous, as frequent replacement of the composite sealing gasket 43 not only insure proper operation thereof to perform its water-sealing function, but insures that the same is maintained in a clean and sanitary condition at all times. As a matter of fact, a new sealing gasket 43 may be employed for each hair and scalp treatment and then discarded, without substantial expense. Finally, an elastic O-ring 49 formed of synthetic rubber, or the like, is sandwiched or placed between the elastic band 44 and the adjacent inner portion of the diaphragm 45, so as positively to insure a Water-tight seal by the sealing gasket 43 with the engaged band of the persons head.

The rear and top central portions of the helmet 40 carry rigid metal structures including a generally horizontal beam 50 and a generally vertical column 51, the front end of the beam 50 being secured to the top central portion of the hood 41 by a suitable fastener 52, the intermediate portions of the colunm 51 being fastened to the rear central portion of the hood 41 by two brackets 53 and 54, and the rear end of the beam 50 and the top end of the column 51 being rigidly secured together, as by welding.

An operating rod 55 is mounted on top of the beam 50 for reciprocation along a generally horizontal axis and fore-and-aft with respect to the top central portion of the hood 41 by an arrangement including front and rear brackets 56 and 57 respectively securely fastened to the corresponding ends of the beam 50, the operating rod 55 projecting through aligned guide bearings, not shown, respectively carried by the brackets 56 and 57.' In order to prevent turning or rotating of the operating rod 55 incident to reciprocation thereof, a guide pin 58 is carried by the operating rod 55 and arranged to project forwardly through a cooperating guide hole formed in the rear bracket 57. The guide pin 58 may be formed of a suitable molded plastic resin, such, for example, as the polyeterafluoroethylene resin sold by Du Pont as Tefion. More particularly, the rear end of the guide pin 58 is fixed to a clamp 59 that, in turn, is securely fastened to the operating rod rearwardly of the rear bracket 57. Also, a clamp 60 is securely fastened to the operating rod 55 forwardly of the front bracket 56. The operating rod 55 is biased into a centered position with respect to the brackets 56 and 57 by two surrounding coil springs 61 and 62, the coil spring 61 acting between the front bracket 56 and the adjacent clamp 60, and the coil spring 62 acting between the rear bracket 57 and the adjacent clamp 59. The rear portion of the operating rod 55 is provided with teeth and constitutes a rack 63 that meshes a cooperating gear 64 that is fixed to the upper end of an upstanding shaft 65 mounted for rotation upon upper and lower bearing brackets 66 and 67 that are rigid fixed to the upper portion of the column 51; and the lower end of the shaft 65 has a V-pulley 68 fixed thereto.

In view of the foregoing, it will be understood that rotation of the shaft 65 first in one direction and then in the opposite direction, and through corresponding angles of rotation, will effect reciprocation of the operating rod 55 fore and aft with respect to its centered position and respectively against the bias of the coil springs 62 and 61; whereby the coil springs 61 and 62 tend to maintain the operating rod 55 in its centered position.

An operating rod 69 is mounted on the rear side of the column 51 for reciprocation along a generally vertical axis and up and down with respect to the rear central portion of the hood 41 by an arrangement including upper and lower brackets 70 and 71 respectively securely fastened to the intermediate and lower portions of the column 51, the operating rod 69 projecting through aligned guide bearings 72 respectively carried by the brackets 70 and 71. The operating rod 69 is biased into a down position by a coil spring 73 surrounding the top end there of, the top of the coil spring 73 being fixed to the extreme top end of the operating rod 69, and the bottom of the coil spring 73 being fixed to a retainer 74 that, in turn, is fixed to the adjacent portion of the column 51. The extreme bottom end of the operating rod 69 carried a rotatably mounted cam follower 75 that engages an eccentric cam 76 carried by the operating shaft 77 of an electric drive motor 78. The intermediate portion of the operating rod 69 is provided with teeth and constitutes a rack 79 that meshes a cooperating gear 80 that is fixed to the rear end of a substantially horizontally disposed shaft 81 mounted for rotation upon a a pair of bearing elements 82 carried by a bearing housing 83 that is securely fastened to the front side of the column 51.

In view of the foregoing, it will be understood that operation of the electric drive motor 78 effects rotation of its operating shaft 77 and the eccentric cam 76 carried thereby, whereby the cam follower 75 in rolling engagement with the outer surface of the eccentric cam 76 effects reciprocation of the operating rod 69. Specifically, the operating rod 69 moves upwardly against the bias of the coil spring 73, and moves downwardly by the action of gravity and by the action of the coil spring 73. As the operating rod 69 is thus reciprocated, the rack 79 meshing the gear 80 causes rotation of the shaft 81 first in one direction and then in the other, whereby the shaft 81 is thus oscillated about its horizontal longitudinal axis and through suitable angles from a neutral position, as established by the stroke of the operating rod 69, asdetermined by the eccentricity of the eccentric cam 76.

The extreme rear end of the shaft 81 has a pulley 84 fixed thereto; and a drive connection, including an endless belt 85', is provided between the pulley 84 fixed to the shaft 81 and the pulley 68 fixed to the shaft 65. The intermediate section of the belt 85 is trained over two spaced-apart guide pulleys 86 that are carried by bracket structure 87 secured to the adjacent portion of the column 51. The guide pulleys 86 respectively engage the opposite runs of the intermediate portion of the belt 85 and are arranged at the intersection of the horizontal plane of the pulley 68 and the vertical plane of the pulley 84.

Accordingly, the previously described rotary oscillation of the shaft 81 effects the previously described reciprocation of the operating rod 55, through the drive connection including the pulley 84, the belt 85 and the pulley 68, together with the shaft 65 the gear 64 and the rack 63. Hence, the operation of the drive motor 78 eifects rotary oscillation of the shaft 81 and longitudinal or axial oscillation of the operating rod 55 for purposes described hereinafter.

Arranged in the upper central portion of the chamber 410 and above the top portion of the head of the person Wearing the helmet 40 is a first applicator 90 having a generally inverted U-shaped configuration, as shown in FIGS. 2B, 9 and l0. More particularly, the applicator 90 comprises an inner metal spring 91 carrying an inner liner 92 formed of latex, synthetic rubber, or other soft material, and an outer metal reinforcing spring 93, the inner spring 91 being securely fastened to the outer spring 93- in any suitable manner, and the inner liner 92 being secured, as by adhesive, to the inner spring 91. Also, the inner liner 92 carries a plurality of spaced-apart and radially inwardly projecting scrubbing fingers or tips 94 that are of soft flexible construction and that are adapted directly to engage the adjacent top and side portions of the hair and scalp of the person Wearing the helmet 40. The elements 91, 92 and 93 are perforated, as indicated at 95, so that water and treatment liquids may readily penetrate the applicator 90 from the exterior and effect contact with the tips 94 and with the haid and scalp of the person wearing the helmet 40. The central portion of the outer spring 93 is rigidly secured to an upwardly directed rod 96 that is adjustably carried in the lower open end of a cooperating upstanding tube 97, rotation of the rod 96 relative to the tube 97 being prevented by a cross pin 98 disposed in a slot formed in the tube 97 and extending through a hole provided in the upper end of the rod 96, and vertical adjustment of the rod 96 relative to the lower end of the tube 97 being effected by a nut 99 carried by a threaded lower outer surface of the tube 97 and cooperating with the pin 98. The upper end of the rod 96 is retained in depressed position with respect to the lower end of the tube 97 by a cooperating coil spring 100 arranged within the tube 97 and engaging the upper end of the rod 96. The extreme upper end of the tube 97 terminates in a sleeve 101 that is mounted upon the extreme front end of the operating rod 55; which sleeve 101 is located in a pocket 410 provided in the top front central portion of the hood 41 and defined by a corresponding upstanding dome section 41d of the hood 41, the pocket 41c being in open communication with the upper central portion of the chamber 41a, as best shown in FIG. 28.

More particularly, the front portion of the operating rod 55 projects forwardly through a hole provided in the rear wall of the dome section 41d and into the pocket 41c; which hole is rendered liquid-tight by an annular sealing grommet 102 carried by the adjacent rear wall of the dome section 41d and disposed in sealed relation with the section of the operating rod 55 projecting therethrough. The sleeve 101 is adjustable longitudinally along the front end of the operating rod 55 and within the pocket 41c; and any adjusted position of the sleeve 101 may be retained by a set screw 103 carried thereby and frictionally engaging the front end of the operating rod 55.

In view of the foregoing, it will be understood that the previously described axial oscillation of the operating rod 55 is imparted to the sleeve 101 carried thereby and arranged in the pocket 41c, and thus to the applicator 90 carried by the sleeve 101 and arranged in the upper front portion of the chamber 41a. At this time, the tips 94 carried by the inner liner 92 are in engagement with the hair and scalp of the person wearing the helmet 40; whereby a corresponding fore-and-aft massage is applied to the front and top portions of the hair and scalp of the person by this oscillation of the applicator 9t Arranged in the rear portion of the chamber 41a and rearwardly' of the rear portion of the head of the person wearing the helmet 40 is a second applicator 110, having a generally dished-shaped configuration, as shown in FIG. 2B. The applicator 110 is of the fundamental construction of the applicator 90 described in detail above; whereby the applicator 110 comprises the elements 111, 112, 113, 114 and 115, respectively corresponding to the elements 91, 92, 93, 94 and 95 of the applicator 90;

'whereby these elements 111, etc., are not here described in detail in the interest of brevity. Thus, it will be understood that the soft flexible fingers or tips 114 are adapted directly to engage the adjacent rear portions of the hair and scalp of the person wearing the helmet 40. The central portion of the outer spring 113 is rigidly secured to a rearwardly directed spindle 116 disposed in a generally horizontal position of alignment with the shaft 81. The rear end of the spindle 116 is adjustably carried in the front open end of a cooperating tube 117, rotation of the spindle 116 relative to the tube 117 being prevented by a cross pin 118 disposed in a slot 117a formed in the tube 117 and extend through a hole provided in the rear end of the spindle 116-, and longitudinal adjustment of the spindle 116 relative to the front end of the tube 117 being effected by a nut 119 carried by the threaded front outer surface of the tube 117 and cooperatting with the pin 118. The rear end of the spindle 116 is forwardly 'thrusted position with respect to the front end of the tube 117 by a cooperating coil spring 120 arranged within the tube 117 and engaging the rear end of the spindle 116. The extreme rear end of the tube 117 is rigidly fixed to a bracket 121 that is mounted upon the extreme front end of the shaft 81; which bracket 121 is located in the extreme rear central portion of the chamber 41a defined within the hood 41.

More particularly the front portion of the shaft 81 projects forwardly through a hole provided in the rear central portion of the hood 41; which hole is rendered liquid-tight by an annular sealing grommet 122 carried by the adjacent rear wall of the hood 41 and disposed in sealed relation with the section of the shaft 81 projecting therethrough. The bracket 121 comprises a pair of rearwardly directed arms 123 between which a guide pin 124 projects and through a hole formed in the front end of the shaft 81, thereby to connect the shaft 81 to the tube 117 via the bracket 121. Also, an adjusting screw 125 is rotatably mounted between the arms 123 and forwardly of the guide pin 124; which screw 125 engages a threaded hole provided in the extreme front end of the shaft 81; whereby the position of axial alignment between the shaft 81 and the tube 117 may be adjusted by proper rotation of the screw 125 in an obvious manner. Finally, one end of the screw 125 carries a knurled part 126, so as to accommodate ready manual adjustment of the screw 125.

In view of the foregoing, it will be understood that the previously described rotary oscillation of the shaft 81 is imparted to the bracket 121 arranged in the extreme rear of the chamber 41a, and thus to the applicator 110 arranged in the rear portion of the chamber 41a. At this time, the tips 114 carried by the inner liner 112 are in engagement with the hair and scalp of the person wearing the helmet whereby a corresponding rotary oscillatory massage is applied to the rear portion of the hair and scalp of the person by this oscillation of the applicator 110.

By way of recapitulation, it is noted that when the chair-like structure 21 is adjusted to suit the comfort of the person who is to receive the hair and scalp treatment, the positions of the applicators 90 and 110 within the hood 41 may also be adjusted to the comfort of the person. Specifically, the vertical position of the applicator within the upper front portion of the chamber 41a may be adjusted by proper manipulation of the nut 99 with respect to the tube 97. Similarly, the horizontal position of the applicator within the rear portion of the chamber 41a may be adjusted by proper manipulation of the nut 119 with respect to the tube 117. These adjustments of the nuts 99 and 119 are made by the attendant or beauty operator to the comfort of the patron or person who is to receive the hair and scalp treatment.

Referring now to FIGS. 1, 2A, 2B and 3, the apparatus 20 further comprises a water supply system including a hot water supply pipe 131 containing hot water under gauge pressure, a cold water supply pipe 132 containing cold water under gauge pressure, a hot water valve 133 disposed in the hot water pipe 131, a cold water valve 134 disposed in the cold water pipe 132, a warm water supply pipe 135, and a mixing valve 136 provided with two inlets respectively connected to the pipes 131 and 132 and an outlet connected to the pipe 135. The valve 133 is of the solenoid-operated type, the solenoid of which is indicated at 133a; and the valve 133 is normally biased into its closed position and is operated into its open position in response to energization of the solenoid 133a. The valve 134 is of the solenoid-operated type, the solenoid of which is indicated at 134a; and the valve 134 is normally biased into its closed position and is operated into its open position in response to energization of the solenoid 134a. The mixing valve 136 is of the thermostatic controlled type and includes a manually operable dial 137 cooperating with an associated index marker 138 and selectively operative to preset the desired temperature of the warm water delivered therefrom to the pipe 135. Thus, when the valves 133 and 134 are opened, both the hot water and cold water are delivered to the mixing valve 136; whereby the thermostatic facility incorporated in the mixing valve 136 operates to cause mixing of the hot water and the cold water to produce warm water in the pipe and having a temperature corresponding to that preset by the dial 137; which mixing valve 136 is of a conventional type.

The hood 41 carries a pair of side nozzles 141 adjacent to the opposite upper sides thereof that are respectively directed downwardly and inwardly toward the opposite upper sides of the applicator 90, and carries a rear nozzle 142 adjacent the rear lower central portion thereof that is directed upwardly and inwardly toward the central portion of the applicator 110. Each of the nozzles 141 and 142 is of the ball-socket type so that it can be adjusted with respect to the direction thereof; each of the nozzles 141 is suitably supported by a base 143 rigidly secured in place in a corresponding hole provided in the side wall of the hood 41; the nozzle 142 is suitably supported by a base 144 rigidly secured in place in a hole provided in the rear wall of the hood 41; each of the nozzles 141 is provided with a water supply tube, not shown, that is connected to the warm water pipe 135; and the nozzle 142 is provided with a water supply tube 145 that is connected to the warm water pipe 135. Thus, when the valves 133 and 134 are opened warm water from the pipe 135 is supplied to the nozzles 141 and 142; the two side nozzles 141 direct two side streams of water onto the opposite sides of the perforated applicator 90; and the rear nozzle 142 directs a rear stream of water onto the central portion of the perforated applicator 110.

Referring now to FIGS. 1, 2B, 4 and 6, the apparatus 20 further comprises a treatment liquids supply system including a number of shampoo liquid reservoirs SR1 to SR7, inclusive, a corresponding number of shampoo liquid dispensers SD1 to SD7, inclusive, a number of rinse liquid reservoirs RR1 to RR4, inclusive, and a corresponding number of rinse liquid dispensers RDI to RD4, inclusive. The shampoo liquid reservoirs SR1, etc., are adapted to contain corresponding different liquid shampoos and are respectively connected to the corresponding shampoo liquid dispensers SD1, etc.; and the 9 shampoo liquid dispensers SD1, etc., are commonly connected to a liquid shampoo supply pipe 151. The rinse liquid reservoirs RR1, etc., are adapted to contain corresponding difierent liquid cream rinses and are respectively connected to the corresponding rinse liquid dispensers RD1, etc.; and the rinse liquid dispensers RDI, etc., are commonly connected to a liquid rinse supply pipe 152. The shampoo liquid dispensers SD1, etc., are Of the solenoid-operated type and are respectively provided with the corresponding operating solenoids SDIS to SD7S, inclusive; and similarly, the rinse liquid dispensers RDI, etc., are of the solenoid-operated type and are respectively provided with the corresponding operating solenoids RDIS to RD4S, inclusive. Energization of any one of the solenoids SD18, etc., effects the discharge from the associated shampoo liquid dispenser SD1, etc., of a measured charge of liquid shampoo into the shampoo supply pipe 181; and subsequent deenergization of the solenoid SD18 causes the associated shampoo liquid dispenser SD1 to receive another charge of liquid shampoo from the associated shampoo liquid reservoir SR1. Similarly, energization of any one of the solenoids RDlS, etc., effects the discharge from the associated rinse liquid dispenser RDl, etc., of a measured charge of liquid cream rinse into the rinse supply pipe 152; and subsequent deenergization of the solenoid RDlS causes the associated rinse liquid dispenser RBI to receive another charge of liquid rinse from the associated rinse liquid reservoir RRl.

The shampoo supply pipe 151 and the rinse supply pipe 152 are commonly connected to a treatment liquid supply pipe 153; and the outer end of the pipe 153 projects through a hole provided in the top central portion of the hood 41 and terminates in a treatment nozzle 154 arranged in the upper portion of the chamber 41a. The hole in the wall of the hood 41 through which the pipe 153 projects is rendered liquid-tight by a grommet 155 carried by the adjacent wall of the hood 41 and disposed in sealed engagement with the section of the pipe 153 projecting therethrough. The treatment nozzle 154 is directed downwardly toward the rear central portion of the perforated applicator 90.

In view of the foregoing, it will be understood that when one of the shampoo liquid dispensers SD1, etc., pumps 3. charge of liquid shampoo into the pipe 151, the same passes therefrom via the pipe 153 and into the nozzle 154; whereby the liquid shampoo is directed by the nozzle 154 in a stream onto the perforated applicator 90. Similarly, when one of the rinse liquid dispensers RDl, etc., pumps a charge of liquid cream rinse into the pipe 152, the same passes therefrom via the pipe 153 and into the nozzle 154; whereby the liquid cream rinse is directed by the nozzle 154 in a stream onto the perforated applicator 90.

Referring now to FIGS. 1, 2A, 2B and 5, it will be observed that the extreme lower rear portion of the chamber 41a formed in the hood 41 communicates directly with the upper open end of a drain tube 160 disposed just rearwardly of the cushion 24a carried by the extreme top end of the back-rest 24; whereby the water, liquid shampoos and liquid cream rinses projected into the chamber 41a drain from the lower rear portion thereof into the upper open end of the drain tube 160. The drain tube 160 is of flexible construction and formed of any suitable, material, such as synthetic rubber. Also, the drain tube 160 extends through the back-structure 26 into the housing 25; and the lower open end of the drain tube 160 communicates with a basin or sump 161 arranged in the housing 25. In turn, the water, liquids, etc., accumulating in the sump 161 are removed therefrom by a drain pump 162 that is driven by an electric motor 163. In the arrangement, the inlet of the pump 162 communicates with the sump 161 via a pipe 164 and the outlet of the pump 162 is connected to a duct or tube 165 extending to drain plumbing, not shown.

Referring now to FIGS. 1, 2A, and 5, it is noted that the apparatus 20 further comprises a hot air supply system that includes a blower or fan 170 that is driven by an electric motor 171. In the arrangement, a shroud 172 is operatively associated with the fan 170; which shroud 172 preferably contains a suitable electric heater 173 and is provided with an inlet 174 communicating with the atmosphere and an outlet 175 communicating with the lower open end of an air duct 176. The air duct 176 may be formed of a suitable flexible tubing that is preferably odorless and insensitive to hot air. The elements 170, 171, 172 and 173 are arranged in the housing 25 and the air duct 176 extends upwardly through the backstructure 26 to the helmet 40. Specifically, the upper open end of the air duct 176 communicates with an opening formed in the upper rear central portion of the hood 41, the upper end of the air duct 176 being secured in place upon the adjacent rear wall of the hood 41 by a cooperating ring 177 carrying fasteners, indicated at 178 in FIG. 2A. Also, a perforated baffle 179 is arranged in the upper rear portion of the chamber 41a forwardly of the upper open end of the air duct 176 and rearwardly and above the applicator which bafiie 179 is secured to the hood 41, as by screws 179', and prevents the blast of hot air that is admitted into the rear portion of the chamber 41a out of the air duct 176 from impinging directly upon the hair and scalp of the person seated in the chair-like structure 21 and wearing the helmet 40.

In view of the foregoing, it will be understood that the air which is taken into the shroud 172 by operation of the fan 170 is heated by the electric heater 173 and then blown through the air duct 176 into the rear portion of the chamber 41a and onto the baffle 179. The hot air passes through the perforated bafl'le 179 and into contact with the hair and scalp of the person wearing the helmet 40 and then passes downwardly through the drain tube into the sump 161. The hot air escapes from the open top of the sump 161 into the interior of the housing 25.

In the arrangement, the air inlet 174 into the shroud 172 may communicate with a series of lower louvers 181 formed in a wall of the housing 25, as shown in FIG. 1, and via a passage containing a removable drawer 182, as indicated in FIG. 1; which drawer 182 may contain a suitable filter, not shown; whereby the air passes through the lower louvers 181 and thence through the filter contained in the removable drawer 182 and then into the inlet 174 of the shroud 172. This arrangement is very advantageous, as it insures that no dust or lint is entrained in the air that is subsequently heated by the electric heater 173 and then passed via the air duct 176 into the chamber 41a in the helmet 40. The hot air that escapes from the open top of the sump 161 into the interior of the housing 25 may pass therefrom back to the exterior via another series of lower louvers 133 formed in the wall of the housing 25, as shown in FIG. 1.

Referring now to FIG. 6, the apparatus 20 further comprises a control circuit that incorporates a program controller 260 that is provided with a rotatably mounted operating shaft 201 carrying a manually operable control dial 202 rigidly secured to the outer end thereof, which dial 202 cooperates with an associated index marker 203. Also, the operating shaft carries a plurality of insulating cams C1, C2 C3, C4, C5 and C6 rigidly fixed thereto, and that respectively control a plurality of armature springs S1, S2, S3, S4, S5 and S6. The spring S1 governs associated front and back switch springs S11 and S12; the spring S3 governs associated front and back switch springs S31 and S32; and the springs S2, S4, S5 and S6 respectively govern front switch springs S21, S41, S51 and S61.

Also, the operating shaft 201 is mounted for longitudinal axial movement, as well as for the rotary movement previously described; whereby the operating shaft 201 carries a contact bridging member 204 that is adapted selectively to bridge an associated pair of front contacts and constituting a line switch. More particularly, when the manual dial 202 is depressed, moved inwardly toward the index marker 203, the operating shaft 201 is moved longitudinally inwardly so as to actuate the line switch 204 into its open position; conversely, when the manual dial 202 is withdrawn, pulled outwardly away from the index marker 203, the operating shaft 201 is moved longitudinally outwardly so as to actuate the line switch 204 into its closed position.

Also, the program controller 200 comprises a shaft 205 that is mounted only for rotary movement; and the outer end of the shaft 205 is connected to the adjacent inner end of the operating shaft 201 by an associated sleeve-like connector 205 that accommodates the relative longitudinal axial sliding-movements of the operating shaft 201 with respect to the shaft 205, while maintaining the normal rotary connection therebetween. Further, the

7 program controller 200 comprises a timer motor TM of the synchronous type, and preferably a Telechron motor. The timer motor TM comprises an operating shaft 206 that is connected to an escapement mechanism 207 that is provided with a driven shaft 207'; and the shafts 207' and 205 are connected together by a friction clutch 208. The friction clutch 208 accommodates manual rotation of the operating shaft 201 by the manual dial 202, without interference by the escap-ement mechanism 207. In the arrangement, operation of the timer motor TM may cause the escapement mechanism 207 to index the shaft 207 through an angle of each seconds in the counter clockwise direction in a wellknown manner. 7

Considering now in greater detail the control circuit, as illustrated in FIG. 6, the same comprises a terminal block, not shown, to which a source of electric power supply of ll8-volts, 60 cycles, single-phase, A-C, is connected; this source including an ungrounded conductor 211 and a grounded conductor 212. Also the circuit includes an interlock or master switch MS, one pole of which is connected to the line conductor 211 and the other pole of which is connected to a conductor 212. The contacts of the line switch 204 respectively terminate the conductor 212 and a conductor 213; and the conductor 213 is commonly terminated by the armature springs S1, S2, S3, S4, S5 and S6. The switch springs S11, S12, S21, S31, S32, S41, S51, and S61 respectively terminate conductors 214, 215, 216, 217, 218, 219, 220 and 221.

Further, the circuit comprises a number of manually operable shampoo selector switches SS1 to SS7, inclusive, respectively corresponding to the solenoids SD1S to SD75, inclusive, and a number of manually operable rinse selector switches RS1 to RS4, inclusive, respectively corresponding to the solenoids RDlS to RD4S, inclusive. Also, the circuit comprises a speed preset device 230 for presetting the speed of operation of the main motor 78, thereby to set the frequency of oscillation of the applicators 90 and 110; which speed preset device 130 consists essentially of a variable resistor 231, an associated shorting wiper 232, a rotatably mounted operating shaft 233 for selectively adjusting the shorting position of the wiper 232 with respect to the resistor 231, and a manual control dial 234 for selectively rotating the operating shaft 233, the control dial 234 cooperating with an associated index marker 235.

In the circuit; the main motor is bridged across the conductors 220 and 221; the terminals of the resistor 231 are bridged across the line conductor 210 and the conductor 221; the wiper 232 is connected to the line conductor 210; the pump motor 163 is bridged across the line conductor210 and the conductor'219; the fan motor 171 and the electric heater 173 are bridged in parallel relation across the line conductor 210 and the conductor 218; the cold solenoid 134a is bridged across the line conductor 210 and the conductor 217; and the hot solenoid 13311 is bridged across the line conductor 210 and the conductor 216. First terminals of the solenoids SD18 to SD7S, inclusive, are commonly connected to the conductor 215; the second terminals of these solenoids are respectively connected to first poles of the corresponding select switches SS1 to SS7, inclusive; and the second poles of these switches are commonly connected to the line conductor 210. First terminals of the solenoids RDlS to RD4S, inclusive, are commonly connected to the conductor 214; the second terminals of these solenoids are respectively connected to first poles of the corresponding select switches RS1 to RS4, inclusive; and the second poles of these switches are commonly connected to the line conductor 210.

Considering now the general arrangement of the control equipment: the master switch MS may be advantageously arranged on the arm-rail 28 carried by the righthand arm-rest 27 of the chair-like structure 21, as shown in FIG. 1, so that the patron or person seated in the structure 21 and wearing the helmet 40 may at any time arrest the program that is being carried out by the 'appa ratus 20 merely by operating the master switch MS into its open position in a convenient and obvious manner. Similarly, the manual dial 137 of the thermostatic mixing valve 136 that presets the temperature of the warm water that is supplied to the nozzles 141 and 142 in the helmet 40 may be carried by the right-hand arm-rest 27, so that this adjustment may be conveniently made by the patron while seated in the structure 21. Similarly, the manual dial 234 of the speed preset device 230 that establishes the speed of the main motor 78 and consequently the frequency of oscillation of the applicators and arranged in the helmet 40 may be carried by the righthand arm-rest 27, so that this adjustment may be conveniently made by the patron while seated in the structure 21. The top wall of the housing 25 may carry a plate disposed just rearwardly of the right-hand arm-rest 27 and the corresponding side of the back-rest 24, as shown in FIG. 1; which plate 190 may carry the manual dial 202 of the program controller 200, the bank of shampoo selector switches SS1 to SS7, inclusive, and the bank of rinse selector switches RS1 to RS4, inclusive; which elements 202, SS1, etc. and RS1, etc., are normally operated by the attendant or beauty operator. Also, in the arrangement of the apparatus 20, the helmet 40 merges into the back-structure 26, at the junction therebetween, as shown in FIG. 1, so that none of the operating mechanism for the applicators 90 and 110 arranged in the helmet 40 are exposed, but rather are housed in the adjacent upper and front portions of the back-structure 26. Thus, all of the operating mechanisms and moving ele ments forming a part of the apparatus 20 are housed either in the back-structure 26 or in the housing 25, so that the chair-like structure 21 has a finished appearance and generally resembles a large upholstered library chair.

Turning now to FIGS. 7 and 8, it will be understood that four independent hair and scalp treatment programs are incorporated in the control cams C1 to C6, inclusive; which programs have been designated: Selection-1, Selection2, Selection3 and Selection-4. Accordingly, the control dial 202 .comprises four start positions and four co- .ordinate stop positions and four coordinate groups of control positions, as illustrated in FIG. 7, and respectively corresponding to the four programs. Selection-1 is the most comprehensive program.and comprises a wetting cycle, a first shampoo cycle, a first water rinse cycle, a second shampoo cycle, a second water rinse cycle, a cream rinse cycle, a third water rinse cycle and a drying cycle; this program consuming 9 /2 minutes. Selection-Q is a less comprehensive program and comprises a wetting cycle, a first shampoo cycle, a first water rinse cycle, a second shampoo cycle, a second water rinse cycle and a drying cycle; this program consuming 8 /2 minutes. Selection3 is a still less comprehensive program and comprises a wetting cycle, a shampoo cycle, a first water rinse cycle, a cream rinse cycle,.a second water rinse cycle 13 prises a wetting cycle, a shampoo cycle, a water rinse cycle and a drying cycle; this program consuming /2 minutes.

The time sequence of the various cycles included in each of the four selections as well as the time durations of each of the included cycles will be readily apparent from an examination of the time-sequence chart of FIG. 8.

Considering now in detail the carrying out of one of the four programs, such, for example, as Selection-l, the beauty operator first selects the one or more ingredients that are to comprise the shampoo liquid to be employed and then closes the one or more corresponding switches SS1, SS2, etc. Also, the beauty operator selects the one or more ingredients that are to comprise the cream rinse liquid to be employed and then closes the one or more corresponding switches RS1, RS2, etc. Next the beauty operator rotates the dial 202 of the program controller 200 into the start position for Selection-J, while the dial 202 occupies its depressed position. It may also be assumed that the patron is comfortably seated in the chair structure 21 and is comfortably wearing the helmet 40, all in the manner previously explained. The beauty operator assists the patron with adjusting the dial 137 to the expected comfortable warm water temperature and with adjustin the dial 234 to the expected comfortable frequency of oscillation of the applicators 90 and 110 incorporated in the helmet 40. Vhen this has been accomplished, the beauty operator lifts the dial 202 in order to cause the operating shaft 201 of the program controller 200 to close the line switch 204. The beauty operator then advises the patron that she may start the preselected program (Selection-l) when she is ready merely by closing the master switch MS. Of course, the beauty operator explains to the patron the controls involving the dials 137 and 234, and notes to her that she may stop and restart the program at any time by control of the master switch MS. It is contemplated that the master switch MS is of a conventional construction, so that upon each operation or striking of its operating plate or button carried by the arm-rail 28, the master switch MS is actuated between its switch positions. Thus, each odd strike of this button closes the master switch MS and each even strike of this button opens the master switch MS in a Well-known manner.

When the patron closes the master switch M8, at this time, the line conductor 211 is connected to the conductor 212 and via the line switch 204 in its closed position to the conductor 213. Connection of potential to the conductor 213 completes a circuit including the elements 86, 861, 221 and 210 for energizing the timer motor TM so as to initiate operation thereof and the consequent timing of the present preset program. Neglecting the controls, for the present, the timer motor TM operates the escapement mechanism 207 via the drive shaft 206; whereby the escapement mechanism 207 indexes the driven shaft 207 step by step each 30 seconds through successive angles of 5 each; with the result that the operating shaft 201 is rotated step by step in the counter clockwise direction and into its coordinate stop position at the conclusion of the program. Also, at the conclusion of the program, the switch springs S6, 861 are opened to interrupt the circuit for operating the timer motor TM. Also, at this time, the beauty operator depresses the dial 202 to insure opening of the line switch 204 so as positively to pre vent closure of any of the control circuits.

Considering now the controls that are carried out in the preselected program (Selectionl), in position #1 of the operating shaft 201, the sets of switch springs S2, S21, and S3, 831 and S4, 841 are closed, as illustrated by the x in each of the corresponding boxes in the chart of FIG. 8. Closure of the switch springs S2, 21 completes a circuit including the elements 211, MS, 212, 204, 213, S2, S21, 216 and 210 for energizing the hot solenoid 133a, so as to effect opening of the hot water valve 133. Closure of the switch springs S3, S31 completes a circuit including the elements 211, M8, 212, 204, 213, 83, 831, 217 and 210 for energizing the cold solenoid 134a, so as to effect opening of the cold water valve 134. Thus, hot water and cold water are supplied to the mixing valve 136, whereby warm water at the temperature preset by the dial 137 is supplied into the pipe 135 and consequently to the nozzles 141 and 142, so that the three streams of water are projected onto the applicators and in the helmet 40. Of course this elfects wetting of the patrons hair and scalp; and the water runs from the chamber 41a via the drain tube into the sump 161. Closure of the switch springs S4, S41 completes a circuit including the elements 211, MS, 212, 204, 213, 84, 841, 219 and 210 for operating the pump motor 163. The motor 163 operates the pump 162, whereby the water accumulating in the sump 161 is pumped via the tube to the drain plumbing, not shown.

In position #2 of the operating shaft 201, the switch springs 82, S21 and S3, S31 are opened to cause deenergization of the solenoids 133a and 134a, so as to effect closure of the valves 133 and 134, thereby to cut-off the supply of water to the nozzles 141 and 142. Also, in position #2 of the operating shaft 201, the switch springs 81, S12 and S5, 851 are closed. Closure of switch springs 81, S12 completes parallel circuits for the several solenoids SD18, SD28, etc., corresponding to the closed shampoo selector switches 881, SS2, etc. These circuits include the common elements 211, MS, 212, 204, 213, S1, 812, 215 and 210, and respectively include the elements 881, SS2, etc.; whereby the several shampoo dispensers SDI, SD2, etc., are operated to effect the pumping of liquid shampoo therefrom via the pipes 151 and 153 to the treatment nozzle 154 in the helmet 40, whereby the liquid shampoo is directed by the nozzle 154 onto the applicator 90 and thus onto the patrons hair and scalp. Closure of the switch springs 85, S51 completes a circuit including the elements 211, MS, 212, 204, 213, 85, 851, 220, 221, 231 and 210 for operating the main motor 78; whereby oscillation of the applicators90 and 110 in the helmet 40 are initiated. Of course, the liquid shampoo and the water in the patrons wet hair produce a lather and the oscillating applicators 90 and 100 shampoo and massage the patrons hair and scalp. It will be appreciated that the above traced circuit for operating the main motor 78 includes at least a portion of the series related resistor 231; whereby the speed of operation of the main motor 78 is inversely related to the part of the resistor 231 that is included in series relation therewith as is determined by the position of the wiper 232. Thus adjustment of the manual dial 234 governs the speed of the main motor 78 in an obvious manner; and the frequency of oscillation of the applicators 90 and 110 is dependent upon the speed of operation of the main motor 78. Accordingly, the arrangement permits the manual dial 234 to adjust the frequency of oscillation of the applicators 90 and 110 to the comfort of the patron receiving the present treatment. Naturally, a relatively high frequency of oscillation of the applicators 90 and 110 produces a more vigorous massage with respect to the hair and scalp of the patron, in an obvious manner.

In position #3 of the operating shaft 201, the switch springs S1, 812 are opened in order to interrupt the previously traced circuits for energizing the several solenoids SD18, SD28, etc., which operation is without effect in the present program, except that the deenergization of the solenoids SD18, etc., causes the associated shampoo dispensers SD18, etc., to operate in order to receive another charge of the liquid shampoo from the associated shampoo reservoirs SR1, etc.

In position #4 of the operating shaft 201, the switch springs 82, S21 and 83, 831 are reclosed, so as to effect reopening of the valves 133 and 134, in the manner previously described, with the result that the warm water is again projected from the nozzles 141 and 142 onto the oscillating applicators 90 and 110 in the helmet 40 so as thoroughly to rinse the hair and scalp of the patron.

In passing, it is mentioned that in the event the temperature of this warm water is not to the comfort of the patron, she may adjust the same by proper manipulation of the control dial 137, in the manner previously explained. The above described water rinsing cycle continues until the operating shaft 201 is rotated into position #8; wherein the switch springs S2, S21 and S3, S31 are opened, so as to etfect reclosure of the valves 133 and 134, in order to terminate this water rinsing cycle. Also, in position #8 of the operating shaft 201, the switch springs S1, S12 are closed, thereby to effect reoperation of each one of the preselected shampoo dispensers SD1, etc., with the result that shampoo is again delivered from the treatment nozzle 154 onto the oscillating applicator 90 and consequently upon the patrons hair and scalp. Of course, the liquid shampoo and the water in the patrons wet hair again produce a lather and the consequent shampooing and massaging of the patrons hair and scalp.

In position #9, the switch springs S1, S12 are opened, so as again to cause the preselected shampoo dispensers SD1, etc., to cycle, so as to receive additional changes of liquid shampoo from the associated shampoo reservoirs SR1, etc.

In position of the operating shaft 201, the switch springs S2, S21 and S3, S31 are reclosed, so as to effect reopening of the valves 133 and 134, with the result that the warm water is again projected from the nozzles 141 and 142 onto the oscillating applicators 90 and 110, so as thoroughly to rinse the hair and scalp of the patron. The above described water rinsing cycle continues until the operating shaft 201 is rotated into position #14; wherein the switch springs S2, S21 and S3, S31 are opened, so as to effect reclosure of the valves 133 and 134 in order to terminate this water rinsing cycle. Also in position #14 of the operating shaft 201, the switch springs S1, S11 are closed. Closure of the switch springs S1, S11 completes parallel circuits for the several solenoids RDIS, RD2S, etc., corresponding to the closed rinse selector switches RS1, RS2, etc. These circuits include the common ele ments 211, MS, 212, 213, S1, S11, 214 and 210, and respectively include the elements RS1, RS2, etc., whereby the several rinse dispensers RDl, RD2, etc., are operated to effect the pumping of liquid cream rinse therefrom via the pipes 152 and 153 to the treatment nozzle 154 in the helmet 40, whereby the liquid cream rinse is directed by the nozzle 154 onto the applicator 90 and thus onto the patrons hair and scalp.

In position of the operating shaft 201, the switch springs S1, S11 are opened in order to interrupt the previously traced circuits for energizing the several solenoids RDlS, RD2S, etc., which operation is without effect in the present program, except that the deenergization of the solenoids RDlS, etc. causes the associated rinse dispensers RDl, etc., to operate in order to receive another charge of the liquid cream rinse from the associated rinse reservoirs RRl, etc.

Also in position #15 of the operating shaft 201, the switch springs S2, S21, and S3, S31 are reclosed so as to effect reopening of the valves 133 and 134, with the result that the warm water is again projected from the nozzles 141 and 142 onto the oscillating applicators 90 and 110 so as thoroughly to rinse the liquid cream rinse from the patrons hair and scalp.

In position #16 of the operating shaft 201, the switch springs S2, S21 and S3, S31 and S5, S51 are opened. Opening of the switch springs S2, S21 and S3, S31 effects S32, 218 and 210 for operating the fan motor 171 and for energizing the electric heater 173. Thus, the fan motor 171 circulates outside air over the air filter arranged in the removable drawer 182 and thence into the shroud 172 and over the electric heater 173 and via the air duct 176 into the chamber 41a in the helmet 40 and thence via the drain duct 160 into the sump 161 and thence into the housing and therefrom back to the outside. Of course, the electric heater 173 heats this current of air that is thus delivered into the helmet whereby the blast of hot air gently penetrates the perforated baffle 179 and contacts the patrons hair so as to etfect a drying action thereupon.

In position #18 of the operating shaft 201, the switch springs S4, S41 are opened so as to deenergize the pump motor 163 in order to arrest operation of the pump 162 by virtue of the fact that by this time all of the water that V shaft in position #20 occupies its stop position coordireclosure of the valves 133 and 134 in order to terminate nate to the start position #1 of this Selection-1, as previously explained; whereby the program of Selection-1 is completed.

At this time, the beauty operator may assist the patron with the removal of the helmet 40, whereby the patron vacates the chair-like structure 21 and proceeds to another site in the beauty shop, wherein her hair may be set or other hair-processing procedures carried out with respect thereto.

In view of the foregoing explanation of the mode of operation of the apparatus 20, in order to carry out the preselected program of Selection-1, it will be understood that the other preset programs corresponding to Selection-2, etc., are carried out in a substantially identical manner in response to corresponding setting of the manual dial 202 of the program controller 200 into its coordinate start position for the other preselected program Selection-2, etc.

In passing, it is mentioned that at any time the patron seated in the chair-like structure 21 and wearing the helmet 40 may interrupt the preset program by momentary operation of the master switch MS and may subsequently restart the preset program at the exact point where it was interrupted by again operating the master switch MS; all without unduly disturbing the carrying out of the overall preset program. Further, it is noted that during the carrying out of a preset program, the patron has some freedom of movement of her head relative to her torso and to the helmet 40, notwithstanding the oscillating of the applicators and in carrying out the cycles in the helmet 40 that are efiected in the program in the manner previously explained. This freedom mentioned is possible by virtue of the construction of the composite sealing gasket 43 arranged between the band about the patrons head and the hood 41 and by virtue of the mounting arrangements of the applicators 90 and 110 upon the respective tubes 97 and 117, as previously explained.

In view of the foregoing, it is apparent that there has been provided improved apparatus for treating a persons hair and scalp that is selectively operative to carry out a P program including preselected cycles, including Wetting,

shampooing, water rinsing, cream rinsing and drying cycles, wherein the preselection may include desired repetition of one or more of the cycles mentioned. Also, the apparatus comprises an improved arrangement of the operating mechanism incorporated in a helmet forming a part of the apparatus'T he apparatus further comprises an improved arrangement of chair-like structure and the helmet mentioned, both forming a part of the overall apparatus.
